+# P1-T4 — Update docs to reflect broker robustness improvements (P2-T1 – P2-T5)
+
+**Status:** In Progress
+**Priority:** P2
+**Dependencies:** P2-T1, P2-T2, P2-T4, P2-T5 (all completed 2026-03-01)
+**Branch:** feature/P1-T4-docs-broker-robustness
+
+---
+
+## Background
+
+Phase 2 broker robustness tasks shipped four user-visible behaviour changes that the existing documentation does not reflect:
+
+| Task | Change |
+|------|--------|
+| P2-T1 | `--broker` flag introduced as the single recommended proxy mode (auto-detects connect vs spawn). `--broker-spawn` and `--broker-connect` become legacy aliases. |
+| P2-T2 | `--broker` / `--broker-spawn` now detect and remove stale socket/PID files automatically before spawning. Manual cleanup is only needed for `--broker-connect`. |
+| P2-T4 | When the broker is unreachable, the proxy writes a JSON-RPC `-32001` error response to stdout instead of silently hanging. |
+| P2-T5 | When `--broker --web-ui` is used but the running daemon was started without `--web-ui`, the proxy prints an actionable warning to stderr. |
+
+The README was already updated to use `--broker` everywhere (completed in P2-T1). The individual `docs/` files and their DocC mirrors were not.
+
+---
+
+## Scope
+
+### Files to update
+
+| File | Changes needed |
+|------|---------------|
+| `docs/broker-mode.md` | Add `--broker` to mode table; update topology, client examples, migration, and limitations sections |
+| `docs/troubleshooting.md` | Update "Could not connect" entry (JSON-RPC error + auto-recovery note); update "Stale recovery" entry; add "Warning: broker without --web-ui" entry; update rollback entry |
+| `docs/cursor-setup.md` | Replace broker mode section with `--broker` primary / `--broker-connect` advanced; update migration note |
+| `docs/claude-setup.md` | Same as cursor-setup |
+| `docs/codex-setup.md` | Same as cursor-setup |
+| `Sources/.../CursorSetup.md` | DocC mirror of cursor-setup changes |
+| `Sources/.../ClaudeCodeSetup.md` | DocC mirror of claude-setup changes |
+| `Sources/.../CodexCLISetup.md` | DocC mirror of codex-setup changes |
+| `Sources/.../Troubleshooting.md` | DocC mirror of troubleshooting changes |
+
+### Files NOT in scope
+
+- `README.md` — already updated (P2-T1)
+- Source code — documentation-only task
+- `docs/webui-setup.md`, `docs/architecture.md` — no relevant changes in P2-T1–T5
+
+---
+
+## Deliverables
+
+1. **9 updated markdown files** — all doc and DocC changes applied
+2. **`SPECS/INPROGRESS/P1-T4_Validation_Report.md`** — quality gate results
+
+---
+
+## Acceptance Criteria
+
+- [ ] `docs/broker-mode.md` mode table includes `--broker` as primary recommended flag
+- [ ] `--broker-connect` and `--broker-spawn` described as legacy aliases in broker-mode.md
+- [ ] Broker mode limitations section no longer says stale files require manual cleanup
+- [ ] `docs/troubleshooting.md` "Could not connect" entry shows JSON-RPC -32001 error format
+- [ ] `docs/troubleshooting.md` "Stale recovery" entry notes auto-recovery for `--broker`
+- [ ] `docs/troubleshooting.md` contains new "Warning: broker running without --web-ui" entry
+- [ ] All three client setup docs show `--broker` as the recommended broker option
+- [ ] DocC sync check passes: `make doccheck-all` exits 0
+- [ ] `ruff check src/` passes (no source changes, should be clean)
+- [ ] `pytest` passes (no source changes, should be clean)
+
+---
+
+## Implementation Notes
+
+- All doc changes are documentation-only; no Python source files are modified.
+- The DocC files in `Sources/XcodeMCPWrapper/Documentation.docc/` are mirrors of the `docs/` files; the project's `make doccheck-all` gate enforces their sync.
+- The `--broker-spawn` and `--broker-connect` flags remain valid (backwards-compatible aliases); docs should note this rather than omit them entirely.

+## REVIEW REPORT — P1-T4 docs broker robustness
+
+**Scope:** origin/main..HEAD (5 commits)
+**Files:** 9 markdown files (5 docs/, 4 DocC mirrors)
+**Date:** 2026-03-01
+
+---
+
+### Summary Verdict
+- [ ] Approve
+- [x] Approve with comments
+- [ ] Request changes
+- [ ] Block
+
+All primary acceptance criteria are met. Two minor gaps found — one missed update in `docs/troubleshooting.md` and one out-of-scope file pair that are now inconsistent.
+
+---
+
+### Critical Issues
+
+None.
+
+---
+
+### Secondary Issues
+
+**[Medium] `docs/troubleshooting.md` "MCP tools are green, but dashboard is unreachable" section not updated**
+
+Lines 309 and 334 still reference `--broker-spawn` as the primary flag:
+
+```
+- `--broker-connect` never starts a dashboard by itself; `--broker-spawn --web-ui` only starts one when it must spawn a host.
+```
+
+```
+3. **Unified broker single-config:** use `--broker-spawn --web-ui --web-ui-config <shared-path>` in all clients…
+```
+
+The DocC mirror (`Sources/.../Troubleshooting.md`) was correctly updated to `--broker` for both of these lines during EXECUTE, but the `docs/troubleshooting.md` source was not. This creates a sync divergence between the two files that `make doccheck-all` does not catch (the check enforces that docs → DocC updates happen together, but does not detect the reverse).
+
+**Fix:** Update both occurrences in `docs/troubleshooting.md` to match the DocC mirror.
+
+---
+
+**[Low] `docs/webui-setup.md` and its DocC mirror `WebUIDashboard.md` not updated**
+
+Both files still use `--broker-spawn` in their multi-agent setup examples (lines 101 and 107 in each):
+
+```
+use `--broker-spawn --web-ui --web-ui-config <shared-path>` across Cursor/Zed/Claude/Codex
+```
+
+These files were explicitly excluded from scope in the P1-T4 PRD ("docs/webui-setup.md — no relevant changes in P2-T1–T5"). However, the guidance is now inconsistent with all other broker docs that use `--broker`.
+
+**Fix:** Update `docs/webui-setup.md` and `Sources/.../WebUIDashboard.md` to use `--broker` in multi-agent examples in a follow-up task.
+
+---
+
+### Architectural Notes
+
+- The `--broker-spawn` legacy alias correctly remains visible in the docs in backward-compat contexts (rollback instructions, stale-recovery notes, "Warning: broker without --web-ui" cause explanation). These references are accurate and should not be removed.
+- DocC sync enforcement (`make doccheck-all`) catches docs→DocC divergence but not DocC→docs divergence. The medium finding above was only caught by manual grep. The sync script could be enhanced to check both directions, but that is out of scope here.
+
+---
+
+### Tests
+
+- `pytest`: 737 passed, 5 skipped — no regressions (documentation-only change)
+- `ruff check src/`: clean — no source changes
+- `pytest --cov`: 91.3% — above 90% threshold
+- `make doccheck-all`: passed — DocC mirrors in sync for all changed `docs/` files
+
+---
+
+### Next Steps
+
+1. **Follow-up task (Medium):** Fix 2 remaining `--broker-spawn` references in `docs/troubleshooting.md` "MCP tools are green" section.
+2. **Follow-up task (Low):** Update `docs/webui-setup.md` and `Sources/.../WebUIDashboard.md` multi-agent examples to use `--broker`.

+#### ✅ P1-T4: Update docs to reflect broker robustness improvements (P2-T1 – P2-T5)
+- **Status:** ✅ Completed (2026-03-01)
+- **Description:** The docs/broker-mode.md, docs/troubleshooting.md, docs/cursor-setup.md, docs/claude-setup.md, and docs/codex-setup.md (plus their DocC mirrors) still reference the old `--broker-spawn`/`--broker-connect` flags as primary options, describe stale-socket cleanup as manual, and omit the new `--broker` flag (P2-T1), auto-recovery behaviour (P2-T2), JSON-RPC -32001 error response (P2-T4), and the web-UI mismatch warning (P2-T5). Update all five docs + four DocC files to reflect the current behaviour.
+- **Priority:** P2
+- **Dependencies:** P2-T1, P2-T2, P2-T4, P2-T5
+- **Parallelizable:** yes
+- **Outputs/Artifacts:**
+  - `docs/broker-mode.md` — mode table, topology, examples, limitations updated
+  - `docs/troubleshooting.md` — stale-recovery, connect-timeout, web-UI mismatch entries updated
+  - `docs/cursor-setup.md`, `docs/claude-setup.md`, `docs/codex-setup.md` — broker examples updated
+  - `Sources/XcodeMCPWrapper/Documentation.docc/` — four mirror files synced
+- **Acceptance Criteria:**
+  - [ ] `--broker` appears as the recommended flag in all broker sections
+  - [ ] `--broker-connect`/`--broker-spawn` demoted to legacy/advanced entries
+  - [ ] Stale-socket recovery described as automatic for `--broker`/`--broker-spawn`
+  - [ ] Troubleshooting entry for JSON-RPC -32001 error present
+  - [ ] New troubleshooting entry for "Warning: broker is running without --web-ui" present
+  - [ ] DocC sync check passes (`make doccheck-all`)

+- **Outputs/Artifacts:**
+  - `docs/troubleshooting.md` — 2 occurrences updated in "MCP tools are green" section
+- **Acceptance Criteria:**

+  - [ ] `docs/troubleshooting.md` "Unified broker single-config" solution option uses `--broker --web-ui`
+  - [ ] `make doccheck-all` passes (mirrors stay in sync)
